MANUALLY OPERATED KEY ATTACHING MEANS Filed March 2, 1953 2 Sheets-Sheet 2 Patented Dec. 25, 1934 MAnUALLrIoP n TEnKEY a Theme- The invention relatesto new and provements, in a machine for attaching-keysto containers; which keys are to be; separatecl from the container and used for opening the same. 3; i ,An; object of the invention-is" to provide. .a

manually. operated device which may beused for bending a portion of akey about the double] seamor some other partof a containerforsecuring. the; same thereto. i i i M A iurther object of the invention is to provide amachine of the above type whichmaybe quick 1y adjusted for operation upon containers-of dif; .Ierent' heights.

myfco-pending application Serial ..No. 659423, filed of even date herewith, there-is shown and described a machine for attaching keys to containers, in which a clinching head travel.-

ing with the container eng es the key, and

bends the same about the doubleseampfithe container. The present invention'has to do with a machine. wherein the clinchinglheadis' mantially operated, the broad invention-being shown 135 and claimed in my co-pending application. f I V [.J {I'hemarzhine includes a supporting base- 1 hav- Ling a gauge member} secured vtheretotb'y aflbolt 'I3 whichmay be utilized for positioriing the con tainer on' the. base. The container is indicated in broken lines inFigcZ at-,4.- Thecontainer'has the end 5 secured thereto by a double. seam 6, which is of the usual construction. The container his. provided with a tearing summonses in broken lines at '1 in Fig. 2, on the tongueor which [4 thekey is placed, and then the strip is rolledon tothekey for opening. the container. The key] is indicated at 8 in the drawings; Said keyh'a's a handleportion 9, and the body portion is slotted at 1l) for the purpose just stated. Extending beyond theslotted portion, the end of the key is "flattened and formed into an open hook 11w This fhook end II is placedov'er the double seam as shown; in Fig. 3, and is thenbent at the extreme outer end thereof under the double seamasin- \55 "'dicated in Fig. 4.v The purpose ofzthe presentma- QAlfi'ed L.

The inner face 30 extends substantially at rightangles to. the face' 29. Thesupporting member 20 is provided witha stem 3 1"whichex- ,tends up throughthe upper, end of the sleeve;19. The sleeve has a recess-32 therein whichis of slightlylarger diameter than the ,stem 31,-. This recess terminates short ofthe top of the sleeve. A spring 33 located in the recess bears against the upper end of the sleeve as an; abutment, and at its lower end against a shoulder on the supporting member. Mounted onthe upper end of the stem 31 is anabutmentplate 3-1.1, l his abutment plate has a threaded connection}with the upper end of the abutment stem 31, :andis held inxadjusted position by a set screw .35.. v

2. When the operator through the handle 39,

turns the segment gear, it will unseat the dog and the clinching head will be moved downward.

In Fig. l of the drawings, the head with the clinching devices is in its -raised-position'. M Thecontainer is placed againstthe gauge on: the sup-.

port with the key resting on the containerlwith the hook end of the key in engagement with the double seam. The operator by turning thehandle 39 moves the head downward until therabutment? plate 34 contacts with the upper end of the bearing of the supporting bracket} During this movement, the support 20"and sleeve move together as a unit, and the-inner clinching device or anvil 21 is brought down into engagement with the key, resting withsuflicient firmness-thereon so as to hold the key placed. At this time, the vertical wall 22 is directly in-contact with the inner face of the hook end.' A continued movement of the handle will lower the sleeve but not the support was the'abut'mentplate 34 is in contact with the supportingbracket, as noted. As thesleeve continuesits downward movement, the abutment 28' will cause the clinching finger'25to swing 'about'its pivotalsupport and'conta'ct with the hooke'nd or the'f key. The inner face of the clinching finger issodimensioned that it will bend the hook 'end underneath the double seam and slide along the hook end producing the bend by the camming action of the inner face of this clinchingfinger; During this bending of the key end there is little or "no strain placed on the container by reason of the fact that the abutment 34 limits the downward movement of the anvil 21. This abutment 34 may beadjusted'andthe pressureonthe key regulated so that it is just suffi'cient to hold the key in place on the double seam during the clinching of the key to the doublesearn. The pressure of the clinching" finger against the keyend is taken bythe anvil 21 at" the-inner portion of the key end, and this-enables the key to be firmly crimped o'rclinched about the double seam. "The key will remain connected tothecontai'ner, and will not be dislodged "through" any handling or storingof theicontainersp- It" may,

however, bequickly released by grasping the handle end ofthe key and'lifting-the same, which will bend the end ofthe key'so as'torelease its connection from the-double seam; a v

'After having clinched the key to the container, the operator turns the handle in the opposite direction' and raises the clinching'head, an'das soon as the sleeve starts on" its upward movement, the clinching finger will be released and th'e'spring 27 will 'move'the' same away from the key end. When the sleeve contacts with the abutment 34, it will lift the support 20 carrying the "clinching fingers and'raise them from the container tothe position shown in Fig. '2. j Thecontainer "can then be quickly removed and'another inserted for It is obvious that minor changes inthe details of construction and arrangement of the parts may be made without departing from the spirit of the invention asset forth 'intheappended claims.
